You probably found that rinsing, or even scrubbing, your hands with only water did a poor job of removing the paint. Soap helps break up the paint and other dirt on your hands, making it easier to remove, along with germs. But even with soap, you have to do a good job washing your hands to remove all the paint. This includes washing them for more than just a few seconds, and getting into all the nooks and crannies where the paint (and germs) can hide.
